IBASE, a leading provider of digital signage players and solutions, has released the SI-122-N dual-HDMI fanless signage player. It’s equipped with 3rd Generation AMD Embedded G-Series SoC featuring high processing performance and optimised for demanding graphics requirements.
The latest offering provides smooth, high-definition video for each display to render the ultimate picture quality to the users. The SI-122-N can be utilised for smart signage displays in high-traffic areas like restaurants, airports, shopping malls, and banks. This helps in conveying dynamic information and targeted promotions, by updating them at strategic times of the day.
Protecting circuits from over current is an important aspect of circuit designing. The cause for over current can be intolerable voltage fluctuation in the power supply, short circuiting, failure of a device or component and overloading. Usually, for the protection of circuits from over current and so the damage from overheating of components, electronic fuses are used in their power supply sections.
Electronic fuses are thin metallic wires which melt down over the passage of a threshold current. In the design of power circuits, apart from electronic fuses, circuit breakers are also used for circuit protection. Any circuit breaker operates like a relay which has the ability to detect a threshold current level and disconnect the rest of the circuit by tripping off the supplies.
LED light is gaining its popularity and replacing all old conventional lights like CFL and other. The most important advantage of LED light is, it consumes very less power and gives very good light. Also LED light operates on DC. So its battery operated, means its portable/mobile.
Another very useful feature of LED light is its intensity can be varied. The LED light intensity can be varied and set as per conditions and requirements. To vary the LED light intensity we have to apply PWM - pulse width modulated voltage.
Touch sensor is very popular input device and nowadays widely used as a replacement of push buttons or keys. A touch plate can be used in place of push button or key to providing an input as logic 1 or 0 to the microcontroller. Touch plate (sensor) is conductive material plate or contact that activates when it comes into contact with human body touch.
The given project demonstrates how to interface such touch plate with arduino. When a user touches the plate with his finger, the arduino detects this touch and indicates this on LED as well as sends the message on a serial port. Here, the program is written in arduino IDE software and compiled using it. It is uploaded into an internal flash of arduino microcontroller ATMega328 through USB built-in programmer.
To meet today’s challenge of transmitting data to a host with as little latency as possible and to simplify the interfacing with modern MCUs, processors and FPGAs, Texas Instruments has developed multiSPI™, an interface that increases data transfer rates between ADCs and digital hosts, while decreasing the required clock frequency. MultiSPI retains compatibility with standard SPI. In multiSPI, throughput is increased buy the use of 4 data output lines and double data rate transfer (DDR), which allows data transfers on both on the rising and falling edge of the SPI clock.
After choosing five finalists from a group of 16 teams, the Google Lunar X Prize Competition(GLXP) has reached its final stage. In this race, 5 teams are now competing with each other for prize money worth 20 Million USD. To register a victory in the challenge, the teams have to launch a spacecraft to the lunar surface, explore it by covering at least 500 meters, and then send back high-definition videos and images.
The first lunar lander, which succeeds to accomplish all these tasks by the end of this year i.e. 31st December 2017, will be declared as the winner. The Google Lunar X Prize teams competing in the final stage include SpaceIL (Israel), Moon Express (USA), Synergy Moon (International), Team Indus (India) and Hakuto (Japan).
If you want to check the level of charging of a battery, then one can use an Arduino battery tester. It can be an attractive tool to detect the leftover battery and then how to use them judiciously. This project is categorized as a basic Arduino project for beginners and hence can be extended to a proper setup.
The project includes equipment like Arduino Uno, Green, red and yellow LED, Zener diode, resistors, and breadboard. The Arduino Battery Tester Circuit is easy to assemble, where the Zener diode is used to test batteries with a voltage greater than 8 volts. This diode allows current to flow in one direction and it reaches the breakdown voltage, from where voltage goes in the reverse direction.
A machine consists of many sub systems working together to perform a certain task. The information from the electronic devices are retrieved from the machine sub systems as binary code. All this information is presented in a user readable formatthrough a display device. The display technology has seen a rapid growth in the past few decades from the old CRT (Cathode Ray Tube) displays to the presently in demand LCD (Liquid Crystal Display) and LED (Light Emitting Diode) displays. The LCDs and LEDs consists of two dimensional arrays of individual display units (pixels) whose number to size of display determines the clarity of the display (resolution).
